Kops: Cross compiling / building

[kris-nova]

I am very reluctant to bring this up, but wondering if we have any plans to support our PC friends?

IE: Cross compiling for Windows..

... Or any other platforms?

[chrislovecnm]

RUN ... no good point. We need to figure it out

[yissachar]

I've started trying to get this to work on my Windows environment which as MsysGit installed.

Issues encountered so far:

1. We assume Unix style env vars separated by :. In Windows they are separated by ;.
2. No sha1sum executable exists. I've created #1924 since we shouldn't really require sha1sum to always exist, only if you are running a command that needs it.
3. Once the above two issues were dealt with I ran into the following:

$ make
go build  -ldflags "" -o c:/Users/yissachar/go//bin/go-bindata k8s.io/kops/vendor/github.com/jteeuwen/go-bindata/go-bindata

Any ideas on how to procede?

[justinsb]

For the separator, I don't know make well enough. We could maybe override GOPATH as well, as we don't really need it, but I worry that would cause more edge-cases. Another option is to build for Windows, but not build _on_ Windows. This is how we produce the MacOS binary, for example.

To add the 3 missing dependencies:
https://github.com/kubernetes/kops/blob/master/docs/development/dependencies.md

Although we can probably start thinking about looking at the official go dep tool now.

[yissachar]

Ah, I guess these dependencies are platform specific? I think that's what was confusing me. I was wondering why there were no issues with the dependencies on other platforms.

In any case, there were other issues with more missing commands, so for now I've taken the path of least resistance and am using the Linux Subsystem for Windows instead.

lucky you @yissachar . im on windows 7!!

get issue when checking out repo:

 git checkout release
fatal: cannot create directory at 'vendor/github.com/docker/distribution/contrib/docker-integration/generated_certs.d/localregistry:5440': Invalid argument

[msnelling]

@shavo007 Getting the same issue, did you make any progress?

[shavo007]

Give up on windows! I run in Ubuntu VM at work or my Mac at home.

[justinliew]

The issue I'm seeing on Windows (Win10+WSL) is with the docker distribution:

fatal: cannot create directory at 'vendor/github.com/docker/distribution/contrib/docker-integration/generated_certs.d/localregistry:5440': Invalid argument

It looks like they fixed this here: https://github.com/docker/distribution/pull/1716 by generating the certs for the integration tests. Is this something we can update to better support Windows users?

[chrislovecnm]

@justinliew more context please

[justinliew]

If I run git checkout release (or go get -d k8s.io/kop) I eventually get the message above. Specifically I think it doesn't like the : in the path.

The docker project fixed this (see PR link in my previous message) by generating these files rather than requiring they be checked out.

This is Windows 10, with WSL (Windows Subsystem for Linux).

[chrislovecnm]

I have kops.exe compiling on osx for windows. If someone wants to take a test drive :) https://github.com/kubernetes/kops/pull/3770

[duizendnegen]

I'd be happy to take it for a test drive @chrislovecnm - I couldn't find the binary attached to the last release, should I look somewhere else?

[chrislovecnm]

@duizendnegen you have to build the binary yourself off of master
